Wise Dan, the two-time Horse of the Year, retained the No. 1 spot in this week's NTRA Top Thoroughbred Poll, but unbeaten Shared Belief jumped from seventh to No. 2 after impressively beating older horses in Sunday's $1 million Pacific Classic.

Wise Dan received 16 of the 40 first-place votes cast this week. Last week the Lexington-based gelding received 22 of 41 top votes. Shared Belief received nine first-place votes this week, having received none the prior week.

Feeling the most fallout, though he did not run, was Palace Malice, who dropped from second to fifth. Kentucky Derby and Preakness winner California Chrome stayed at third with eight first-place votes.
